New Katy Perry track praised as she mixes politics and pop

Katy Perry has delighted fans with the release of a new track just days ahead of her appearance at the Grammy Awards this weekend.

The US pop star unveiled reggae-inspired Chained To The Rhythm on streaming service Spotify and YouTube, as well as on radio stations globally, after teasing it on social media earlier in the week.

The song features Bob Marley’s grandson Skip Marley, was penned by Katy and Sia, and produced by Max Martin, who worked with the artist on her breakout single I Kissed A Girl.

While the track became widely available on Friday, Katy had given fans the chance to listen to it early if they managed to locate one of the specially-placed disco ball music players that were strewn all over the world.

One fan, who had made it to the only UK-based disco ball in London’s Leicester Square, told BBC Newsbeat they thought it was the “best promotion ever”.

She sings: “Are we crazy? Living our lives through a lens, trapped in our white-picket fence, like ornaments, so comfortable, we live in a bubble, a bubble, so comfortable, we cannot see the trouble, the trouble.”

One fan wrote on Twitter: “Katy Perry has made subtly political banger about dancing your troubles away. I heart it.”
